我有一个文件：
<extend-configuration-property name="gin.ginjector.extensions" value="test.client.gin.ClientInjectorAdditional"/>
我的ClientInjectorAdditional为：
public interface ClientInjectorAdditional extends Ginjector {
NotificationFetcher getNotificationFetcher();
}
现在，我想在我的入口点类中注入NotificationFetcher。我试过了
public class Test implements EntryPoint {
private static final ApplicationController controller = GWT.create(ApplicationController.class);
@Inject
private NotificationFetcher notificationFetcher;
@Override
public void onModuleLoad() {
controller.init(;
...
}
}
问题是没有注入notificationFetcher。
如何将GWTP与ginjector扩展一起使用？
编辑：
当我使用
private final ClientInjectorAdditional injector = GWT.create(ClientInjectorAdditional.class);
我收到以下警告：
No gin modules are annotated on Ginjector interface test.client.gin.ClientInjectorAdditional, did you forget the @GinModules annotation?
编辑：
我试过了：
@GinModules（{ClientModule.class}）公共接口ClientInjectorAdditional扩展了Ginjector {...}
但这会产生以下错误：

GWTP与其所有演示者和视图获取者自动创建ginjector。它还支持为非GWTP对象扩展该ginjector。这是您的操作方式：
一种。定义一个接口，在some.package.client包中将其命名为GinjectorExtensions
package some.package.client;
public interface GinjectorExtensions {
//your objects here
MyConstants getMyConstants();
MyMessages MyMessages();
MyRequestFactory getRequestFactory();
}
b。编辑您的GWT模块xml文件以包括以下行（告诉GWTP将您的代码行添加到它的autogen Ginjector中）：
<set-configuration-property name="gin.ginjector.extensions"
value="some.package.client.GinjectorExtensions"/>
然后，您只需在任何地方@Inject您的对象，一切都将按预期方式工作。
编辑：检查完您的代码后，只需从ClientInjectorAdditional中删除“ extends Ginjector”，一切都会正常进行。
